Index of the first cell in jagged array in C#

Question

What is the index of the first cell (the first left cell in first line and first row) in jagged array in C#?

a[0][0]?? 
a[0][1]??

Answer 1

If your array is defined as int[][], then the first line would be a[0], and the first cell a[0][0]. I should suggest that you try to find out such simple things by experiment.
